Security before growth
If a feature would weaken the shield, we don't ship it. Ever. Our customers' trust is the product.
KareriAI — AI security, researched & built in-house
AI should be safe
AI should be safe
by default, not by luck
KareriAI is the security lab behind KareriAI Labs. We study how AI systems get attacked — so the teams building on them can ship without fear.
Our mission
Make AI security invisible infrastructure
Every platform shift created a new attack surface — and a new generation of defenders. The PC era gave us antivirus. The web gave us the WAF. The cloud gave us CSPM. The AI era deserves the same: protection that's fast, transparent and always on.
That's what we build. Not another dashboard to babysit — a shield that sits silently between your users, your models and everyone trying to exploit the conversation.

What we believe
Three rules we never break
Transparency by default
Every block, every redaction, every rule is explainable. No black-box verdicts — users and auditors both deserve the "why".
Speed is a feature
Security that adds latency gets bypassed. Sub-12ms protection means the shield stays on — because nobody notices it's there.

A small team with long histories in offensive security, ML research and building infrastructure that cannot go down.
